DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selection processing method in an information processing apparatus such as a personal computer and an electronic organizer.

[0002]

2. Description of the Related Art Conventionally, when a plurality of objects are simultaneously selected by using a pointing device, a starting point and an ending point are designated, and an object included in a rectangle formed by the starting point and the ending point is selected. It has been common practice to select individual objects one by one while pressing a specific key.

[0003]

When a plurality of objects are simultaneously selected in a personal computer or the like, a starting point and an ending point are selected by a pointing device, a rectangle is generated by the starting point and the ending point, and the rectangle is included in the rectangle. The object was selected.
